Good for Press, Bad for Amber

So this week I am discovering the differences between my job at The Daily Athenaeum and The WVU Press. I've had some problems adjusting to looking for errors in Chicago style of writing, rather than Associated Press style. While I worked at the DA, I was totally emersed in AP style and used it on a daily basis. Now, I've got to get used to Chicago, which I knew slightly before I started at the Press, but am not nearly as strong in as AP style. This has been an issue in copy editing the website and I've really been having trouble catching all of the errors in Chicago style, so I've got to go over everything again. This is frustrating, but I'm learning all the same.
I had to quit my job at the DA in order to fulfill my duties at the Press, but I don't think any of my supervisors realized this. From this I have learned to communicate when I quit other jobs to my higher ups in the future. Anyways, this transition from newspaper to publishing company and the kind of writing they do is presenting some challenges to me in the way I write and edit. When I was told to look over the stuff I had already copy edited I was pretty disappointed in myself for not catching all of the mistakes I should have. However, it is times like these when I realize why I had to leave the DA. It wasn't just because I needed more time in my schedule in general, it was also because I had learned all I could from the DA and it was time to move on to where I could learn more skills involved with writing and editing. Even though it was discouraging to know I messed up, I also understand that this is helping me become as marketable as possible for the stuff that happens after I graduate in May.
